ASP.NET通过自定义函数实现对字符串的大小写切换功能

public string ToggleCase(string input)
{
 string result = string.Empty;
 char[] inputArray = input.ToCharArray();
 foreach (char c in inputArray)
 {
 if (char.IsLower(c))
 result += c.ToString().ToUpper();
 else if (char.IsUpper(c))
 result += c.ToString().ToLower();
 else
 result += c.ToString();
 }
 return result;
}

public string ToggleCase(string input)
{
 string result = string.Empty;
 char[] inputArray = input.ToCharArray();
 foreach (char c in inputArray)
 {
 if (char.IsLower(c))
 result += Char.ToUpper(c);
 else
 result += Char.ToLower(c);
 }
 return result;
}
